This blank experiment shows that the Au-free uranium oxide it- self is inactive at 350 °C below. When gold nanoparticles are in- duced into inorganic oxide, the activity is affected greatly by the oxide supports. The authors prepared SiO2, Al2O3, UO3, and CeO2- supported gold catalysts by the impregnation method and compared their WGSR activities. The following activity order is
376 380
Au/U O 38
Au/UO 3
384 388
O1s
392 396
Au/U 3O8
